Who this list is for
Newly acquired discus need a separate, temporary observation space before introduction to an established aquarium. This quarantine tank checklist is for water care, monitoring, and dedicated equipment, not treatment instructions.
How to use this list
Set the 40-gallon breeder aquarium or larger on the bare-bottom tank mat and secure the lid. Install the adjustable heater, backup heater, digital thermometer, two sponge filters, air pump, airline tubing, and two check valves. Prepare water with aquarium-safe water conditioner and check it with the freshwater liquid test kit. Add PVC elbow hides, set the dim aquarium light on its timer, and label the dedicated fish net, siphon hose, and bucket so they do not move between tanks.
Common mistakes
Do not share the net, siphon hose, or aquarium bucket with the established aquarium. Avoid a cluttered setup that makes observation difficult; PVC elbow hides provide simple cover without filling the tank. Do not rely on memory for water changes or observations when a water-change logbook and waterproof marker are listed.
What is on this list
The checklist includes the larger tank, two heaters, duplicate sponge filtration, aeration supplies, water conditioner, test kit, and ammonia alert badge. It also covers a dim light, timer, dedicated maintenance tools, and a logbook. Cross off the equipment you already have, but keep dedicated quarantine items separate.
Before you go
Choose a stable location with room for the breeder aquarium, air pump, and bucket. Confirm that the backup heater, filters, tubing, and check valves match the tank. For concerns about discus health, consult an aquatic veterinarian or qualified clinician rather than adding products not listed here.
